Abstract (en)
Systems and methods for resonance detection are disclosed. For example, one method for resonance detection includes the step of transmitting an actuator signal to an actuator coupled to a surface of a device. The actuator signal is configured to cause the actuator to output a force to the surface. The method further includes the steps of receiving a response of the surface to the force; determining a resonant frequency of the surface based at least in part on the response; and outputting a signal indicative of the resonant frequency.
